  This patch has been developed as part of the DPDK Userspace Summit Hackathon.
It provides a PoC for code-coverage analysis for the DPDK project.

To generate the report, a developer simply follows the official
meson coverage workflow, described in [1].
In doing so, both an HTML report, as well as an XML version is generated
for further processing.

In short, the following steps are required:

- install gcovr
- meson -Db_coverage=true build-cov
- meson compile -C build-cov
- meson test -C build-cov --suite fast-tests
- ninja coverage -C build-cov

+1 for this effort, I also think that would be a great addition so show
our current coverage via a service or something like coveralls.io and
possibly the dashboard.  I don't know if coveralls would support the
series branches we create, so I will spend a bit of time looking into
it.

BTW, can you also include information on the current coverage % of code
base?  Last I recall, some of the libraries were quite low (bpf and
bbdev stick in my mind as having very low coverage).
